A card is randomly drawn from a standard 52-card deck. Find the probability of thegicen event. A queen and a heart.

'thegice' What is this meant to be?

There are 13 hearts in the deck and 4 queens but one of those queens is a heart, so the number of favourable events is 13+4-1=16

The probability of choosing a queen or a heart on the first draw is 16/52 ==> 4/13

Was that your questions?
